Potential consumer response to the healthy symbol proposed by the U.S. food and Drug Administration

Abstract

The U.S. Food and Drug Administration (FDA) has proposed updates to the definition of “healthy,” including distinctions between types of sugar and fats and limits on added sugar, saturated fat, and sodium. To communicate the updated standards, the FDA is developing a Healthy symbol to display on food packages, which could reduce knowledge gaps by assisting U.S. consumers in meeting recommended nutritional guidelines. This study aimed to explore the potential for the label to increase consumers' ability to correctly identify a food product that met the FDA's criteria for a healthy symbol. To complete the study objective, 1018 adults were recruited to represent the U.S. population regarding gender, age, income, and geographic region, and a randomized group experiment was used to determine the potential communication value of an FDA Healthy symbol. Respondents were randomized to a group shown either a healthy yogurt with the FDA symbol, a healthy yogurt without the symbol, or an unhealthy yogurt. Respondents were then asked whether they considered the yogurt shown to be healthy, a question examining the desired criteria for the Healthy symbol, willingness to accept various costs to implement the symbol, and questions to measure objective dietary knowledge. Adding the symbol to yogurt that already met the healthy criteria only yielded about a 4 percentage point increase in the proportion of respondents identifying it as healthy. However, 53 % of participants still identified a yogurt too high in added sugars as healthy. For the desired label criteria, 64 % of respondents selected limits on added sugars, 57 % selected limits on sodium, and 54 % selected limits on saturated fats, which all align with the proposed updates to the definition of healthy. Over half of the participants supported the implementation of the label, even at a cost of $40 annually, and 86 % supported implementation at no cost.
